Application filed December 5, 1911. Serial No. 664,084.

provements in Self-Couplers for Fluid Train-Lines; and I do hereby declare that the following is a full, clear, and exact description of the same. 0

The invention relates to improvements in self couplers for fluid train lines, as described in the present specification and illus trated in the accompanying drawings that form part of the same.

The invention consists essentially in the novel construction and arrangement of parts, whereby the steam, air and other fluid lines are connected by the meeting of flexibly arranged jaws having valves extending through their faces, these valves controlling fluid lines.

The objects of the invention are to eliminate the use of hose couplings and to avoid the dangers incident to manually operating such couplings, and generally to devise a form of coupler automatic in its operation, simple in regard to its parts and economical in respect to its maintenance.

In the drawings, Figure 1 is a perspective view of one member of the coupler. Fig. 2 is a horizontal sectional view of the members in their coupled position. Fig. 3 is a front view of the coupler with the valve casing cover removed and the valve casing in section. Fig. 4 is aperspective detail, showingan inside view of. the valvecasing cover. is an enlarged longitudinal sectional view of the valve casing cover.

Like numerals of reference indicate corresponding parts in each figure. 1

Referring to the drawings, and particularly to one member of the coupler, 1 is a valve casing having a plurality of interior chambers 2, said casing extendin rearwardly and forming part of the s ank 3, said shank having a corresponding number of passages at therethrough leading respectively to the interior chambers 2. 5 is an inwardly flanged guide member extending forwardly from said shank 3 and forming with said valve casing the pockets 6 adapted to recelve the valve casing of the other membet; ,to the coupling. '1 is the cover of the valve casing 1, closing the interior chambers 2 and having holes 8 therethrough leading into said chambers. 9 are valves each formed with the stem 10 and the head 11, said head having the port 12 registeringwith the corresponding port in the other coupling member and thelateral port 13 leading into said port 12 and out through the side of the head. The head 15 flanged at 1 1 and abuts the inner side of the cover 7 around the hole 8, and therefore, in the extreme outer position of the valve 9, the port 13 is closed by the wall of the hole 8. 15 are springs, each of said sprmgs encircling said stems 10 between the cover 7 and the plate 16 and retaining said valves in their outer position, except on the application of pressure on the heads 11.

The plates 16 are supported a short distance from the inside of the cover 7 by the posts or screws 17, but it must be understood that any sultable arrangement will do for this as said plates may be supported on rigid flanges from the inside of the cover, or may be themselves in the form of brackets, as long as the parts form a support for the inner ends of the stems 10 and allow a certain inward movement for said valves, as shown where the stems project through the holes 18.

It will now be seen that in corresponding coupler members, the jaws will meet, the valve casing in each instance entering pockets 6 and as the two covers 7 are rought to bear one on the other, the heads 11 which project outwardly from the cover in the form of a button, come in contact and press inwardly one on the other, with the result that the ports 12 register and the ports 13 are opened by the inward pressure which bring said ports 13 beyond the inner face of said cover, with the consequence thatv there are free and interrupted passages from the interior chambers of the one coupler member to the interior chambers of the other coupler member and through into the train lines.

19 are the bodies of the coupler members, each of said bodies having an outwardly the recesses 24, one bearing against. the upper said flanges 21 and forming recesses 24 and a central front opening 25 in alinement with the central rear opening 26 between the flanges 23.

27 are spring-held bars extending across within the interior of the body 19 into side of the shank and the other bearing against the lower side thereof. 28 are springs at theends oi the bars 27, between said bars and said body, thus said bars are i flexibly supported fromthe body.

29 are flanges extending outwardly from the inner end of the shank 3.

30 are pins extendin from the flanges 23 into the recesses 22 and through the flanges 29, said flanges sliding readily on said pins. 31 are springs encircling the pins 30 between sald flanges 29 and the rear walls of the recesses 22.

It will now be understood that the shank of the coupler member must beinserted through the openings 25 and 26 in order to bring the flanges 29 against the rear side of the side flanges 23, so that the pins 29 extend through said flanges. The result of this arrangement is that the flanges 29 are ordinarily held up tightly against the said side flanges 23 with the result that the coupler member is held to a forward position. The said shank 3 also passes between the bars 27, therefore, on every side said coupler member is flexible.

32 are flexible tubes secured to the inner end of the shank 3 and communicating with the ends of the passages 4: and at their other endssecured to the train line pipes.

What I claim as my invention is:

1. In a self coupler for fluid train'lines,

a pair of coupler members, a valve casing on o the fore end of each coupler member, each of said members being formed with a shank integral with the valve casing and a guide plece flaring outwardly from said valve casing and forming therewith a pocket, a cover 130 through which said stem extends, a spring between said bracket and said cover and holding the head of said valve in its outward osition and adapted to close a communicatmg port in said valve, a pair of bodies secured to the car bodies and flexibly supporting said shanks, flexible means of communication between shanks and the train lines adapted to connect said train'lines with the valve chambers in said coupler members. 2. In a self coupler for fluid train lines, a pair of coupler members each of said members being formed of a pierced shank terminating at the front end thereofin a valve casing and a guide piece, said guide piece,

and saidvalve-casing forming a pocket, a valve spring-held'to its outer position and extending into said valve casing, a pair of bodies secured to the car bodies and having openingstherethrough, each of said bodies havinginwardly extending flanges forming rear and front recesses, a pair of bars engaging a shank on the upper and lower sides respectively and spring-held at their ends to the upper and lower sides of the body, flanged pieces extending laterally from said shanks to the rear of inwardly extending flanges in the body and springs extending into the rear recesses and flexibly holding said flanges from the shank in their forward position, and flexi'ble means of communication from said shanks to the train lines.
